I had the 5 Star Tune done on my last class C. Yes it did improve the mileage a tad.
The important thing it did was while on cruise control it took a significant (read that as real grade) to cause the trans to downshift. When it did downshift on rolling hills like on I90 in South Dakota the tachometer did not go to 4k rpms. I suspect part of that was due to the extra torque the engine was producing along with other computer wizardry.
All of the above was with Tow/Hall on.
thank you for the real time reply.. most of my 3000 mile was loaded and towing a 3800lb. car with most of the time a almost full water and fuel
thanks again for the reply
